SANITARY DRINKING-CUP.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed July 12, 1913. Serial No. 778,652.

ments in Sanitary Drinking-Cups,'of which the following is a specification.

This invention relates broadly to drinking cups, and specifically to a sanitary pocket drinking cup. I The primary object of the invention is to provide a drinking cup adapted to be conveniently carried in the pocket, which 18 of simple, inexpensive and durable construction and wherein the fluid receptacle, when not in use, is wholly inclosed and protected from contamination.

A further object is to provide a cup of the character mentioned comprising a fluid receptacle and a holder therefor, said fluid receptacle being conveniently and detachable with respect to said holder and, therefore, readily renewable.

With these and other objects in view, the

invention resides in the features of con-' struetion, arrangement of parts, and combinations of elements which will hereinafter b'e exemplified, reference bcin had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of the invention; Fig. 2 is a vertical section through the casing, showing the fluid receptacle and holder in side elevation and disposed within said casing; Fig. 3 is a side elevation of said receptacle and holder detached from the casing, showing said parts as they appear when the receptacle is filled with uid; Fig. 4 is a top plan view of the same; and Fi. 5 is av partial detail section of the hoiiler and easing. illustrating a modification.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views-1 indicates a bag-like receptacle composed of a suitable flexible or collapsible material, as aper, close-woven silk. or o'.ner fabric, and having, preferably, a downwardly-tapered form, as shown. Formed on, or attached to, the outer surface of said receptacle as by stitching, is a plurality of longitudinally extending strips 2, pre erably of the same material as the rece tacle, between the body-portions of whic and the receptacle attachable are constituted rockets adapted for receiving the resilient fingers 3 of a sheet-metal holder, designated generally by the numeral 4. Said holder comprises a hollow cylindrical portion 4 having a closed end 5 with an annular flange (3, and said fingers 3, the latter being integral with and projecting from said cylindrical portion at spaced distances apart and being normally flexed or sprung outward slightly in spread relation. The cylindrical portion 4 of the holder preferably has threads pressed therein adapted to enact with threads 7 formed ad.- jacent to the open end of a tubular inclosiug barrel or casing 8 within which the receptacle and holder are contained when not in use. As is obvious, however, the portion 4 of the holder and the casing 8 may, if desired, be left plain and unthreaded, as shown in Fig. 5, m which case their respective positions are retained by frictional engawement. m

Vhen detached from the casing, the receptacle is held partially expanded by the natural resilience of the fingers which, as

'hereinbefore indicated, are normally flexed or sprung outward with respect to the axial line of the holder 4. When filled with fluid, the weight of the latter acts to com letely expand the receptacle, as shown in igs. 3 and 4. To reintroduce the holder and receptacle in the casing, the fingers 3 are drawn inward at their outer ends, collapsing said receptacle, until the same are of such compass as will ermit their insertion in the open end of t e casing.

From the foregoing it will be seen that I provide an extremely simple, durable and convenient form of sanitar drinking cup which is admirably adapte to be conveniently carried in the pocket, occupying, as it does,'but little more s ace than an ordinary fountain pen. It Wlll further be noted that the receptacle 1 may be instantly removed from the holder and another substituted, as occasion or the condition of the rece tacle may require.

t will be obvious that various changes or alterations within the scope of the appended claims may be resorted to without departing from the general s irit or scope of the invention; hence, I 0 not wish to be understood as limiting myself to the precise construction and arran ement of parts herein shown and described.

Having thus described my invention,

hat I claim as new, and desire to secure by Letters Patent, isi 1. A drinking cup comprising a cylindrical member having a lnrality of spaced fin-v gers projecting there rest. a collapsible receptacle detachably. mounted on said fingers, and a casing adapted for receiving said member and receptacle.

2. A drinking cu comprising a collapsible fluid receptac e resilient supportm means disposed in em racing relation to said r ceptacle, and a tubular inclosure in which said receptacle and supporting means are receivable.

3. In a drinking cup, a fluid receptacle composed of collapsible material, a holder for said receptacle comprising a cylindrical member having a plura ity o integral resilient fingers pro'ecting therefrom and disposed at space intervals about and substantially parallel to a common axis, and a casing or inclosing said receptacle and holder.

4. In a drinking cup, a cylindrical memher having a plurality of fin ers formed integral therewlth and dispose about a common axis, said fingers eing resilient and normall inclined outward with respect to said axis, a collapsible fluid receptacle detachabl mounted on said fingers, and a cas ing within which said receptacle and fingers are adapted to be introduced. 5. In a drinking'cup, a cylindrical member having a lurality of fingers formed integral.therew1th and dis osed about a common axis, sail fingers eing resilient and normall inclined outward with respect to said axis, a collapsible fluid receptacle disposed withln the embrace of said fingers, means detachably connecting said receptacle to said fingers, and a casing adapted to receive said receptacle and said fingers.

6. A drinking cup com rising a collapsiblc' fluid receptacle, a p urality of members dis 'osed in supporting relation to said rcce tac c and adapted in one position to hol the receptacle 1n spread condition and in another osition to hold the same in collapsed con ition, and a receiver for inclosing said receptacle and members.

In testimony whereof, I afiix my signature in presence of two subscribing witnesses.
